All very true, but I have heard running aluminum heads since they cool more rapidly than steel will run cooler and effectively act as if you have one less point of CR such as 10:1 steel and 9:1 aluminum. Is this not the case? Like I said previously, I have no problem running race fuel I have already implemented a blend but I plan to run more of a blend if not straight race fuel.
